Finally decided on which way to go with my lighting setup as I really would like to have them dimmable. I was going to use LD11,S controlled by Homevision but decided on using C_Bus.
C_bus is a lighting control system designed and manufactured by Clipsal here in Australia...I believe the first version was released around 1994 ...It works on a 2 wire bus connected to all C_Bus units...this bus also supplies the power for the C_Bus units (36v dc)
